[Evaluation of syndrome X by exercise stress thallium-201 SPECT].
Using exercise stress thallium (Tl)-201 SPECT, we studied 11 patients with Syndrome X who had anginal pain and ischemic ECG change during exercise in spite of angiographically normal coronary artery. In three patients, the initial stress image showed mild hypoperfusion in the area of ST segment depression, but the delayed image showed complete or incomplete redistribution. Eight cases showed normal perfusion. This result suggests that some patients of Syndrome X could be caused by small vessel disease.
